Roth IRAs. Half of any income that results from a rollover or conversion to a Roth IRA from another retirement plan in 2010 is included in income in 2011, and the other half in 2012, unless you elected to include all of it in 2010.

Terrorist attacks. You can exclude from income certain disaster assistance, disability, and death payments received as a result of a terrorist or military action. For more information, see Publication 3920, Tax Relief for Victims of Terrorist Attacks.

Gulf oil spill. You are required to include in your gross income payments you received for lost wages, lost business income, or lost profits. See Gulf oil spill under Other Income, later.

Qualified settlement income. . If you are a qualified taxpayer, you can contribute all or part of your qualified settlement income, up to $100,000, to an eligible retirement plan, including an IRA. Contributions to eligible retirement plans, other than a Roth IRA or a designated Roth contribution, reduce the qualified settlement income that you must include in income. See Exxon Valdez settlement income under Other Income, later.

Foreign income. If you are a U.S. citizen or resident alien, you must report income from sources outside the United States (foreign income) on your tax return unless it is exempt by U.S. law. This is true whether you reside inside or outside the United States and whether or not you receive a Form W-2, Wage and Tax Statement, or Form 1099 from the foreign payer. This applies to earned income (such as wages and tips) as well as unearned income (such as interest, dividends, capital gains, pensions, rents, and royalties). If you reside outside the United States, you may be able to exclude part or all of your foreign source earned income. For details, see Publication 54, Tax Guide for U.S. Citizens and Resident Aliens Abroad.

Disaster mitigation payments. . You can exclude from income grants you use to mitigate (reduce the severity of) potential damage from future natural disasters that are paid to you through state and local governments. For more information, see Disaster mitigation payments under Welfare and Other Public Assistance Benefits, later.

Nonqualified deferred compensation plans. In most cases, all amounts deferred under a nonqualified deferred compensation plan for all tax years are included in gross income for the current year, unless certain requirements are met. See Nonqualified deferred compensation plans under Employee Compensation, later.

Qualified joint venture. A qualified joint venture conducted by you and your spouse may not be treated as a partnership if you file a joint return for the tax year. See Partnership Income under Business and Investment Income, later.

Photographs of missing children. The Internal Revenue Service is a proud partner with the National Center for Missing and Exploited Children. Photographs of missing children selected by the Center may appear in this publication on pages that otherwise would be blank. You can help bring these children home by looking at the photographs and calling 1-800-THE-LOST (1-800-843-5678) if you recognize a child.

You can receive income in the form of money, property, or services. This publication discusses many kinds of income and explains whether they are taxable or nontaxable. It includes discussions on employee wages and fringe benefits, and income from bartering, partnerships, S corporations, and royalties. It also includes information on disability pensions, life insurance proceeds, and welfare and other public assistance benefits. Check the index for the location of a specific subject.

In most cases, an amount included in your income is taxable unless it is specifically exempted by law. Income that is taxable must be reported on your return and is subject to tax. Income that is nontaxable may have to be shown on your tax return but is not taxable.
